Microservices vs. Monolith for Scalability and Efficiency
summary
Argues concrete tradeoffs: internal function calls run around 1 ms internal calls while service-to-service adds 50–100 ms API latency, microservices increase infrastructure and onboarding costs but cut scaling costs, and maintenance can fall over time. Gives a decision framework of complexity, scale, team structure, and 3–5 year growth, cites Netflix moving from a failed monolith to 700 microservices handling 2 billion API requests/day, and recommends starting with a modular monolith and extracting services as needed.
